Project description:To determine genes regulated by HNF1A in 22Rv1, we performed siRNA mediated knockdown of HNF1A using pooled siHNF1A (L-008215-00-0005 5 nmol) and pooled siSCR purchased from Dharmacon. RNA was harvested 3 days after transfection and gene expression profiling was performed. Similarly to determine genes regulated by HNF1A in LNCaP, we performed retroviral transduction of LNCaP cells in duplicate for HNF1A and empty vector control expression. cDNA for HNF1A in RC211201 vector (origene) was subcloned into a murine stem cell virus (MSCV)-based retroviral vector with hygromycin selection marker (Addgene). After 3 days of transduction, cells were selected for four days in hygromycin and later on RNA was harvested for gene expression profiling.
Project description:HNF4G, AR, FOXA1, H3K4me1, H3K27acetyl binding sites upon knockdown and overexpression of HNF4G in 22Rv1 and LNCaP prostate cancer cells respectively
Project description:HNF4G is a gastrointestinal tissue enriched master transcriptional regulator seen overexpressed in a subset of prostate cancer. Here we have mapped binding sites of HNF4G, AR, Foxa1, H3K4me1, H3K27acetyl upon knockdown and overexpression of HNF4G in in 22Rv1 and LNCaP cells respectively
Project description:FoxA1 has been shown critical for prostate development and prostate-specific gene expression regulation. In addition to its well-established role as an AR pioneering factor,several studies have recently revealed significant AR binding events in prostate cancer cells with FoxA1 knockdown. Furthermore, the role of FoxA1 itself in prostate cancer has not been carefully examined. Thus, it is important to understand the role of FoxA1 in prostate cancer and how it interacts with AR signaling. To address these questions, we generated engineered LNCaP cells with FoxA1 knockdown using shRNA or siRNA, 22RV1 cells with stable FoxA1 knockdown and PC3M cells with FoxA1 stable overexpression. We performed microarray analysis of these cells. We performed microarray analysis on LNCaP cells with FoxA1 knockdown using shRNA or siRNA, 22RV1 cells with stable FoxA1 knockdown and PC3M cells with FoxA1 stable overexpression
Project description:SChLAP1 is a novel long non-coding RNA expressed in prostate cancer. Here we performed transcriptional profiling of the prostate cancer cell lines LNCaP and 22Rv1 comparing non-targeting siRNA treatment versus SChLAP1-siRNA treatment. Goal was to determine the effect of SChLAP1 knockdown on gene expression in prostate cancer. Two-condition experiment: non-targeting siRNA versus SChLAP1 siRNA treated cells. Biological replicates: 1 control replicate, 2 treatment replicates. Technical replicates: 3 replicates per SChLAP1 siRNA. Cell lines: 22Rv1 and LNCaP.
Project description:Here we performed transcriptional profiling of the prostate cancer cell lines LNCaP and 22Rv1 comparing non-targeting siRNA treatment versus siRNAs targeting SWI/SNF complex proteins (SMARCA2, SMARCA4, and SMARCB1). Goal was to determine the effect of SWI/SNF knockdown on gene expression in prostate cancer. Two-condition experiment: non-targeting siRNA versus SWI/SNF-siRNA treated cells. Three SWI/SNF proteins were targeted: SMARCA2, SMARCA4, and SMARB1. Biological replicates: 1 control replicate, 2 treatment replicates per SWI/SNF protein. Technical replicates: 1 replicate per SWI/SNF protein. Cell lines: 22Rv1 and LNCaP.
